Audi A4 B9 Active Lane Assist retrofit

    Hello, Ladies & Gents,

    I just bought my friend brand new Audi A4 S-line 190 Quattro and I am looking to get some help regarding a retrofit. I did not tick the Driver's Assistance Package because a) loads of useless things in it b) nearly 80% of the package consists of stuff you already have on your vehicle when you have S-line trim but they just enable the code. Probably you are paying £1300 for the radar sensors, to be honest.

    Anyway back on topic. The only thing I am very keen to have is the Active Lane Assist. Not to be confused with Lane Change Assist. What I need is the button on the indicators lever to activate the active lane assist assuming above 52m/h to keep the vehicle in the lane using the front Audi pre-sense Basic camera(not the parking one) to keep me in the lane. Now the problem is that that switch has 7 versions. Version with ACC, version active lane assist and ACC, the version with all the above plus the rear washer activation(Avant) and the list goes on. What my vehicle has is only Cruise control, nothing else. It's a Saloon, no rear washer, no ACC, no high beam assist(although I do not think it makes any difference as there is no specific hardware for it correct me if I am wrong though), only normal CC plus the active lane assist switch. To give you all a clue I have narrowed it down to a certain part number so If anyone knows more about this or can verify and confirm my part number is what I need please let me know. 4M0907129GT....all are Zeros by the way, not o.

    Thank you in advance and looking forward to your answer

    The driver assistance package comes with an upgraded front camera - not sure if that is required for lane assist? If you change it you'd have to calibrate the new one, which is a PITA.

    Also check if the A4 has a separate image processing control module (for the camera); if so, you might need a different one to support lane assist. Knowing Audi, it won't be as simple as a new control stalk!

    Personally I find ACC a lot more useful than lane assist, which is a bit...meh. I've had it in my last two Audis but wouldn't rush to retrofit it.

    You can get this company to help https://www.kufatec.co.uk/shop/en/audi/a4/a4-8w/active-lane-assist-audi-a4-8w Needs QK1 which might be the camera https://www.kufatec.co.uk/shop/en/audi/a4/a4-8w/front-camera-audi-a4-8w They are also stating you'll need a different windscreen.

    All uk models that are S-line + trim level have the QK1 pre-installed because it uses it for Audi pre sense Basic which also comes as standard( yes ze Germans give standard equipment- amazing). For example, I could now download and enable Traffic Sign Recognition. I literally just need the part number for the appropriate steering column. Plus obviously the code for my MMI for the settings. I consulted 3 retrofit specialists as well but no one is willing to risk buying the wrong steering column and end up stuck with a £201 steering column switch. And I can see why, when I went to TPS they confirmed that you have no images all anything. Just model codes. So anyone with prior knowledge on this that done it before would be of great help.

    I see you have already posted in Audiworld, which was going to be my next suggestion. They tend to be ahead of us in mods so hopefully the thread they've linked you to will be of some help. Have you tried the parts link at the top of the B9 forum, or a parts request here https://www.audi-sport.net/xf/support-tickets/list

    when i have time i will look for the right steering colom. Do you know have the text "speed" or "limit" on your CC switch?

    look for your current PR codes and look for the PR code for Lane Assist :) add them together and search for your column

    Hi, thanks a lot for your reply. I was looking for an online search engine for Audi parts. I have 7 parts which I know they are wrong. So now it is just a process of elimination and hopefully, it will be the right one. Can I also ask if you know the PR code for the active lane assist by any chance? Thank you, again.
    And by the way, my car does have speed limiter, CC(standard), no high beam assist(although I don't think it makes any difference because I have seen A4s with high beam assist and it has no visual difference) and it is a Saloon so no rear washer.

    @Eilleen The pre-sense doesn’t use a camera. You need the camera that only comes with Matrix lights for the Active Lane Assist to be coded. This can be activated easily with OBDEleven.
